HAVE JUST COMMENCED THE PUBLICATION OF
The Illustrated Library of Wonders.
This Library is based upon a similar series of works now in course of issue in France, the popularity of which may be inferred from the fact that
OVER ONE MILLION COPIES
have been sold. The volumes to be comprised in the series are all written in a popular style, and, where scientific subjects are treated of, with careful accuracy, and with the purpose of embodying the latest discoveries and inventions, and the results of the most recent developments in every department of investigation. Familiar explanations are given of the most striking phenomena in nature, and of the various operations and processes in science and the arts. Occasionally notable passages in history and remarkable adventures are described. The different volumes are profusely illustrated with engravings, designed by the most skilful artists, and executed in the most careful manner, and every possible care will be taken to render them complete and reliable expositions of the subjects upon which they respectively treat. For THE FAMILY LIBRARY, for use as PRIZES in SCHOOLS, as an inexhaustible fund of ANECDOTE and ILLUSTRATION for TEACHERS, and as works of instruction and amusement for readers of all ages, the volumes comprising THE ILLUSTRATED LIBRARY OF WONDERS will be found unexcelled.
The following volumes of the series have been published:—
